Spatial variability of soil properties in field experiments introduces an extra source of variation and inflates experimental error, thus masking true treatment effects. Data from a field experiment i ... Read More
Soaking of cotton seeds prior to sowing and then rubbing in ash is a common practice to -facilitate germination under adverse soil conditions. But little has been reported of the effects of various pr ... Read More
The study was designed to evaluate the effects of tillage types including deep-ripping, conventional and zero tillage on compaction, using selected physical properties of agricultural soils.Particle s ... Read More
This field experiment on fababean was conducted with three rates of N (20, 100 and 200 kg/ha) as urea (labeled with 5%, 1% and 0.5% l3N a.e. respectively) and barley was grown as reference crop. Resul ... Read More
A study pertaining to Zn application to two sorghum cultivars, grown under two moisture regimes was conducted. Zinc was applied @ O, 1, 3, 9, or 27 mg kg'1 soil. Zinc concentration and uptake by both ... Read More
A field study was conducted to investigate the effect of five levels of zinc (0. 5, 10, 15. 20 kg ha'1 ) and three levels of boron (0, 0.5 and 1.0 kg ha') on yield and yield components of wheat under ... Read More
A greenhouse pot experiment was conducted to compare growth, P uptake and P efficiency of wheat and triticale at various stages of growht as affected by P fertilization. The results showed that applic ... Read More

The study to evaluate the effect of sowing dates and row spacings on growth and yield of four Brassica napus genotypes was conducted during fall season 1994-95. Plant height, number of primary branche ... Read More
Pore size and shape distribution control hydraulic properties and root penetration. It changes with profile development and management practice. Changes in pore size distribution in a Typic Us tort he ... Read More
Most of the tree species can be propagated through seeds; however, the seedlings require sufficient root growth and nutrient availability to attain proper size at the time of planting. The application ... Read More
The experiment was conducted in metallic pots (25x25x25 cm), open at lower end, placed in trenches. Three application levels of N labelled ( NHJ2 $0^ and two levels of' N labelled straw were used to s ... Read More

Studies were undertaken to evaluate commercial sodium chloride (NaCI) as an extract ant of exchangeable ammonium (NHJfrom soil with the objective of reducing the cost of N analyses. Ten soils differin ... Read More
Soil texture is an important aspect of a soil profile and particle-size distribution also has a significant role in most of the soil properties. Soil texture of three profiles (Caemarfon, Lleiniog, an ... Read More
A number of soil sampling procedures (stratified random, zigzag, strip and regular, grid) were cbmpdred with the traditional random soil sampling and composite soil sampling. Soil samples were collect ... Read More
Two methods of organic carbon estimation were employed on three soil profiles (Caemarfon brick works, Lleiniog, & Penmon-buried profile; all belong to Salop series), formed on calcareous parent materi ... Read More
In rainfed area, soil crusting is one of the major problems having different intensity in different soils. A field experiment was conducted to find out the most suitable soil crust management practice ... Read More
